WINTER-Tools in Aerospace Industry
Grinding of power plant components has always been making great
demands on grinding technology, because of the stock removal
characteristics of materials like Inconel, Nimonic und WASP alloy.
These are known as highly long-chipping and therefore tend to clog
the grinding wheel’s topography.
In general, two grinding technologies – and with it two kinds of
abrasives are used:
- CD-Grinding (Continuous
Typical for this method is
continuous dressing: chips getting caught in the bond are removed
before next contact with the component.
The CD method is known as extremely high-wear on grinding wheels as
well as on dressing tools. In grinding wheels, less costly cutting
materials are used (aluminium oxide (Al2O3)
or silicium carbide (SiC).
- Grinding with intermittent dressing
this method, dressing of a constant dressing amount is required
according to a given number of ground components. More and more
often, grinding wheels with superabrasive materials cBN and
diamonds are used.
In both techniques, the wheels are dressed with diamond roller

Turbine components like blades or combustor cases consist of
unhardened long chipping materials like Inconel, Nimonic or WASP
These materials are extremely wear intensive on the layer of
grinding wheels. Accordingly, requirements are high towards the
specifications of the layers.
Due to the loss of profile accuracy, conventional grinding
wheels are often used with CD grinding (CD: continuous dressing
The permanent dressing process consequently makes frequent
changes of the grinding wheel necessary.
In addition the dressing tools have an extremely high wear,
Because of the high wear, the use of grinding tools with
superabrasives (diamond, cubic Boron Nitride (=cBN)) is not
recommended in combination with the CD grinding process.<
Due to the much better profile retention, these tools do not
need to be dressed continuously.
Especially vitrified bonded cBN grinding tools are increasingly
used in this field of application.
